Auto AC Refrigerant Recharging Complete Tool Kit with 3.5CFM Single-Stage Rotary Vane Vacuum Pump (3.5CFM, 150Micron/29.91Hg, 1/4HP), Manifold Gauge Set, Quick Coupler and R134A Can Tap/Opener Valve

Bought this kit because I could not get a plumber to come out the the acreage and commission my slit phase A/C Unit. Does the job very well. Good quality guage set and pump for my needs and pretty much exactly as described. Do not hesitate to purchase this kit...it's great. Don't forget to get the 1/4" adapter mentioned in other reviews to be able to use it on the heat pump valves. Thank you to the other reviewers that made this clear to me when I bought mine. Only plumber that called back wanted $3,000....this pump kit was a lot less lol. Lots of video's on the interweb of how to do this as well....Enjoy.

Muy buen equipo, hay que leer el instructivo y respetar los ciclos de trabajo y descanso.

This pump pulls vacuum as good as big brand units. I used it a few times so far on various vehicles and it has never failed to get all the way down to 29 or 30 in a few minutes. No regrets so far. It's well built, so I think with proper care it should last a long time.

I would always go to the local auto parts store and would rent this same exact unit for 350 dollars. Of course, your not losing money since it comes back within a couple of days. But I started to think, that hundreds of people are using the same loaner tool and sometimes it wouldn't be cleaned. Then I looked at Harbor Freight because of their prices but I read the reviews. Then I found this one, loved it from day 1. Plus, it comes with a carrying case that can be stored anyway. Price is really good and guages are of high quality. Buy this, even if you don't have an AC shop. This saves you money from going to the mechanic and/or going to use loaner tools.

Works perfect for the job . I used it to put the ac in vacuum and evacuate moisture from the system . Also used it to add ac to system The gauges and fitting works well . Thanks also for sending oil for the Vacuum pump . The price was affordable also . In my country it get real cold for several month . So most ac system sits for an average of 7 month Most issues with ac here is mainly leaks from shwader valves . So am in business .
